That's quite a batch of springtails you've got there.

Your best bet is to remove and rinse your worms with dechlorinated water and start a nice, new clean worm bin, with new substrate. Be sure to remove all springtails or they'll start again. Keep the new bin away from the old.

Sell those springtails. We dart lovers and vivarium builders love them. Just be sure there are no mites in the batch if you do sell them. If you don't need them or want them you can bleach them and then dump them outside.
